Hello,

Water has been sitting in the passenger and driver side sills and got on the center console wiring as well (broken sunroof and clogged drains). The radio volume doesn't work, terrain response doesn't work but all lights are on, key fob doesn't unlock and lock (tried splicing the green wires, no luck, might be corroded all the way through the wire), and "D" is illuminated all the time on gear shifter. I have tried searching and reading but nothing I have tried has worked so far. I replaced the terrain control with all the switches, tried splicing the green wires for the key fob. Is there one specific issue for all, or is it multiple issues? Where to start?Audio System

I can only advise on the gear shifter issue, it'll need to be replaced as the PCB on the side will have shorted out. I flooded the console when i left the sunroof open and we had a flash summer storm, managed to dry everything else out and not have any further problems but the shifter wasn't so lucky.
I would have thought that replacing the switch packs on the console will have fixed it but must be further along the harness.
